BEFRIGERATING APPARATU.

Application filed January 19, 1922.' Serial No. 530,235.

The invention relates to refrigerating apparatus and its object is to improve the construction set forth in Letters Patent No. 1,284,964, dated Nov. 19, 1918.

' The invention consists inthe several novel features hereinafter set forth and more particularly defined by the claim at the conclusion hereof.

In the drawings: Fig.-1 is a longitudinal section of a machine embodying the inven: tion. Fig. 2 is a transverse section. is a detail section showing the refrigerant inlet to the compressor. 'g. 4 is a horizontal section taken on line 4+4of Fig. 1. Fig. 5 is a view'partly in plan and partly in section of the base and parts therein. 4 i

The invention is exemplified in a structure provided bottom 7, a circular side wall 8, a cross-wall- '9, inwardly extending flanges 10 adjacent its-top o'n which the..compress'or casing is mounted, an extension ll projecting'from one side forming a bed for the compressor motor and a flange 12 under said, bed, all integrally formed or cast in onepiece.

A compressor casing comprising cylinders 13, a cylinder-head 15, a crank-case 14, and a lower head 16, which is provided with laterally extending lugs 17 which are secured on flanges 10 of the base by bolts 18. The lower head 16 and lugs 17 are secured together by bolts 20. One side of the crankcase is provided with an opening which is closed by a head 21 which is removably secured to the case by bolts '22. The other side of the case is provided with a similar opening and is closed by a head 23 which is removably secured to the case by bolts 24. A shaft 25 extends through a packingbox 26 in head 23 and is mounted in a bearing 27 in said head and a bearing 28 in head 21. A combined fly-wheel and belt-pulley 29 is secured to the outer end of shaft 25. An.

oil chamber 30 is formed in and inte rally with head 23 and is provided with a' lling pipe 31 with a removable cap 31 in its upper end which is disposed adjacent the top of: the chamber in which the compressor is located. integrally formed eccentrics 32 are secured to the shaft 25 and each operates a pitman 33 which has its upper end pivoted to one of the compressor pistons 34 which are slidably mounted in the cylinders 13. Each piston is provided with an inlet check-valve 35. An outlet check-valve 37. is

slidably mounted in the upper end of Fig. 3.

with a base 6 which comprises a:

.refrigerant line,

each cylinder and is normally closed by a spring 38.

The low side 39 of'the refrigerant line extends under the motor bed 11 through a packing box 40 in the-Wall 9' and to a port 41 formed in a fitting 42 which is secured to one slde of the compressor cylinders, the port 41 being in communication with a duct 43 which leads to the cylinders and is in communication with the inlet check-valve 35; .A pipe44 is connected to the outlet duct 4oirom check-valves 37 and is coiled around the compressor cylinders to form a condenser 46 and extends thence downwardl and is connected, at 47, to the top of a liquid rece1ver.- j

The liquid receiver is disposed in base 6 and comprises a vertically cylindrical wall 48 and a bottom 49 and a top 50.which are welded tothe wall 48. A pipe 51, which leads to the usual expansion valve in the is connected to the wall 48 of the receiver, at 52, and through a' packing box 53 provided in the wall 9 and under the motor bed. The receiver 48 is e ccentri-.v

eally disposed in the base 6 for convenience in providing room :fo'r vertically extending pipe connections. The top of thereceiver is confined between flanges 10.

A water jacket surrounds the compressor and condenser and is secured to the top of the base by said bolts. An internal ring 58 is Welded to the upper end of'skirt 54 and a head 59 removablylsecured to ring 58 by bolts 60 forms a removable cover for the .water jacket. A'water supply pipe 61 ex:

tends-under the motor bed 11 and is connected to wall 9 to discharge water into the chamber in base 6. An outlet pipe 62 extends through a packing box 63 in wall 9 and is provided with an upwardly extending member 64, the upper end of which is open and terminates ad acent the top of the water jacket so that the water delivered into the base by pipe 61 will circulate around the receiver, compressor casing and condenser and overflow into member 64 of the outlet provided with a flange 57' -the base 6, the chamber in the latter being pipe. This construction lsone which permits the water under pressure to be used. An electric motor 65 issecured on bed 11 by bolts 66 and a belt 67 is adapted to drive the drive-wheel 29 for the compressor from a pulley 69 on the shaft'of said motor.

The outer face of-the head 23 is formed to fit against and conform to the skirt 54. and leakage at this point is prevented by a packing 70, washer 71 and bolts 72 which is closed by a removable cap 75. The oilpipes 74 and 31 are extended to the topiof the water jacket so they can be readily filled.

The invention exemplifies a refrigerating apparatus in which the parts are compactly arranged, and in which provision is made for access thereto in event of a break down, The construction is one which can be produced at a low cost and by reason of its compactness, is well adapted to form the operating unit of a domestic refrigerating system. By pro-. viding an integral or common base for the compressor and motor, the correct operating relation between them will be maintained and the machine in its entirety can be mounted in a. small space.

The invention is not to be understood as restricted to the details set forth, since these may be modified Within the scope of the appended claim, without departing from the spirit-and scope of the invention Having thus described the invention, what I claim as new and. desire to secure by Letters Patent, is: v

In refrigerating apparatus, the combination Ora horizontally extending base pro-' vided with an upwardly extending wall having an open top and forming a water chamber, a compressor secured on the top of the base above the chamber, a skirt havingan open base, extending and forming a water jacket around and enclosing the compressor, and having its lower end removably secured to the top of said base,'said jacket being in communication with and forming an upward continuation of the water; chamber in. the base, acondenser disposed in the jacket and connected to the compressor, a refrigerant receiver formed separately from the base disposed in the water chamber and insertable andremovable through the open top of the base wall, a connection in the jacket between the condenser and the receiver, water inlet and outlet connections for the Water chamber, and refrigerant connections for the receiver and the compressor passing through the base. v v
